AWESOME!This is PSSC Curriculum guys!
Look for "PSSC Films Academic Film Archive of North America". Real physics. Some of the viewers to this site just might remember when legitimate physics was taught in school. It was fun. It was interesting! "Something" happened in our public school system between then and now... and this isn't the place for pontificating.. well, just watch the old PSSC films and enjoy.

Boom goes the dynamite
Somewhat longish film featuring a bit of a rough looking scientist telling us all about crystals featuring stuff "you can get from the drugstore" and you can make them with "the instructions that come with this film". Well, it's 2015 pal, and I don't know any drug store that sells alum. Anyways, lots of demos are shown, some are neat, some not so.
